Co-authorship 2.0: patterns of collaboration in Wikipedia
Abstract The study of collaboration patterns in wikThe study of collaboration patterns in wikis can help shed light on the process of content creation by online communities. To turn a wiki's revision history into a collaboration network, we propose an algorithm that identifies as authors of a page the users who provided the most of its relevant content, measured in terms of quantity and of acceptance by the community. The scalability of this approach allows us to study the English Wikipedia community as a co-authorship network. We find evidence of the presence of a nucleus of very active contributors, who seem to spread over the whole wiki, and to interact preferentially with inexperienced users. The fundamental role played by this elite is witnessed by the growing centrality of sociometric stars in the network. Isolating the community active around a category, it is possible to study its specific dynamics and most influential authors.fic dynamics and most influential authors.

Conclusion "The results mark a considerable differenc"The results mark a considerable difference with respect to most of the scientific collaboration networks: very low values of mean distance and diameter, a quite low and decreasing clustering coefficient, and disassortative mixing by degree. We find evidence of a strong centralization of the network around some stars, a considerable nucleus of very active users, who seem to be omnipresent." "The disassortativity of the networks is a signal that the most active contributors tend to interact with the less experienced users, spreading over the whole wiki, rather than to collaborate with each other. In this continuous relationship between the core and the periphery of the community can perhaps be found one of the constituting characteristics of the Wikipedia community."aracteristics of the Wikipedia community."
